Guild quest did not properly credit

Last night a guildmate and I worked on a DMG DEALER fleet quest, "Deal 50000 damage while fleeting with a guildmate". Over the series of 8 matches I dealt 33,838 damage and my fleetmate dealt 13,942 damage excluding any boosts. However, 10+ hours later it only shows me having dealt 11,694 damage, and my fleetmate isn't even listed. Even if my fleetmate forgot to choose that quest during the series of battles (though he claimed he did), I'm obviously missing 2/3 of my damage dealt. I reviewed all quests and we are marked with the fleeting icons.

I'm fairly certain about halfway through the 8 matches I saw it at that 11k damage number and no progress since.

 

As a followup, I eventually found the subtext that said it only applied to a win. It would be a lot clearer to add a couple words to the description and delete the subtext and, as "Deal 50000 damage during wins while fleeting with a guildmate". This confusion was compounded by the use of a booster (the numbers weren't adding up) and that my guildmate didn't selecting the guild quest even though I asked him directly and he said yes.

 

I think it shows clearly enough. Just my opinion though
